To aid 107mm fr 'lrmg coiwcz'io:

Be it known that we, Gno. 1*]. Hxioirr, of Milford, (Jonneeticut, \VM.H. \Vooi), of Hartford, Connecticut, and \VM. 1E. \VINsOR, of New York,N. Y., have invented certain new and useful Improvements in Means forHeating and Controlling Gases for Motors, of which the following is aspecification, reference being had therein to thc'aecompanying drawings.

This invention relates to the method ofheatiug the gas to produceexpansion for use in the class of motors which are driven by theexpansion ofcompressed gas under high p ress are, as carbonic-acid-gasengines and others of that class, and is especially intended for use ingas engines for torpedo-boats; also, to de tails of construction of thedevices used for such engines, especially the gas-supply therefor.

The object of our invention is to produce a rapid expansion of the gasafter it leaves the flask or holder,where it isheld in a compressed orliquefied state, and before it enters the engine, and to preventrefrigeration, due to such expansion.

The special features of our-invention will be hereinafter pointed out inthe claims.

In the drawings, Figure 1 is a longitudinal section of the shell of atorpedo-boat, showing in a general way the arrangement of the parts orcompartments of the boat. Fig. 2 is a longitudinal section of cylinderwhich contains the expansion-coils and chemicals. Fig. 3 is across-section thereof. Fig. at is a plan view of the lime-chamber. Fig.5 is an end view of the expansiou-cylinder,showing device for (lumpingthclime-chamber. Fig. 6 shows the cover, and Fig. 7 its mode ofattachment enlarged.

In Fig. 1, A is a flask or chamber in a torpedo-boat, adapted to containcarbonic acid, nitrous oxide, or similar gases. The pipe which conveysthe gas from the reservoir to the en gine passes through compartment B,over the top of the expansioircylinder to the throttlevalve S, thenreturns, and is passed back and forth in the cylinder 7), then out tothe engine in compartment 1). The reel of cable by which the boat isguided is in the compartment C.

\Ve give this as a convenient and desirable arsomewhat smaller indiameter than the eompart-ment B of the boat in which it is placed, soas to leave room above said cylinder or flask for the passage of pipesand wires. In the lower portion of cylinderb the pipe to is coiled orstored, having a sufficient number of turns to bring a considerableamount of surface in contact with any liquid which may be put in thevessel Z). The cylinder 1) is partly filled with a mixture of sulphuricacid and water,

which can remain for a considerable time in contact with the pipewithout special damage thereto. Other acid and alkaline agents thanthose herein mentioned may be used.

Above the coiled pipes a there is a lime chamber, 0. Thislime-chamberis1i relerably a trough having journals at each end, which journals passthrough the heads (I of the cylinder 1). The trough, a side view ofwhich is shown in Fig. 2, may be a pipe with a section or side removed.

The journal ehas a gear-wheel, attached thereto, which engages with aworm, g, the shaft h of which leads to the outside of the boat, where itmay be turned by a key or crank, thus revolving the chamber or trough 8o0 in its bearings. The open portion of the trough c is covered,preferably, by a sheet of rubber, c, which is strengthened at the edgesby wires 0. X'Vhen the trough is filled with lime, the cover 0 iscemented thereon to retain the lime in place. The edge 0* of the cover 0is connected with the shell of the cylinder 7) by wires or chains i,which may be attached to hooks or rings 1i inside said reservoir.

Thus when the lime-chamber is revolved on 0 its axis the cover 0, beingretained by said connections, will be torn off from the trough orchamber, and the contents of said chamber will be dumped.

The operation of our device is as follows: 5

The gasreservoir being chargcdwith gas,

the flask to the throttle-valve, then through a,

where it absorbs the heat developed by the chemicals in contact with thecoils of pipe a,

and is rapidly expanded and all danger of refrigeration avoided. The gasat once passes to the engines to propel the boat, and then escapesthrough the exhaust, or is condensed by suitable apparatus.

WVe claim- 1. The method herein described of expanding the gas in asupply-pipe, which consists in bringing a supply of lime suddenly intoconfact with a body of chemicals of the character described, saidchemicals being in contact with the feed-pipe leading to the engine, asset forth.

2. The combination of the expansion-chamber, the pipes therein, and thelime-chamber,

arranged as described, so that the lime-chainber may suddenly dump itscontents into the expansion-chamber, as set forth.

3. The combination of the flask, apipe lead,- ing to the engine, anexpansion cylinder, through which said pipe passes, and a throttle-valvearranged between the flask or reservoir and the expansion-cylinder.

4. The combination, with the reversible dime-chamber, of the coversecured thereto,

and devices, substantially as described, for tearing off the cover whenthe chamber is re- .versed.

5. The combination of the cylinder I), having pipes therein, asdescribed, the limechamber 0, having a cover, devices for removing saidcover, and the worm-gear and shaft .leading to the exterior of the boat,for reversing the lime-chamber, as set forth.

In testimony whereof we affiX our signatures in presence of twowitnesses.
